Suggestion: Search All _______ (Main Category)

I would like to see selections under the "Look in Topic" dropdown that span entire main categories. For example:

Area Editor (All Forums)
Dawn Of Time (All Forums)
Forum - How to use it (All Forums)
MUSHclient (All Forums)
PennMUSH (All Forums)
ROM (All Forums)
SMAUG (All Forums)

Typically, I want to recall a thread which I know is in one of the MUSHclient forums, but I don't know offhand which specific forum it is in. Searching "(All Topics)" yields too many results, and searching each specific forum is too much of a pain in the arse.

Good idea. Check out the search page now. :)

Thanks Nick. :)
